1 Claim.

The present invention relates to improvements in wrench construction.

An object of the invention is to provide a wrench designed for gripping and turning objects of varying contour.

Another object of the invention is the provision of a wrench constructed so as to effect a tight, non-slipping grip upon an object.

A further object of the invention is to provide a wrench of .the aforesaid character which can be quickly fitted in the gripping position on or released from an object.

Still another object of the invention is the provision of a wrench having a flexible binding element and means for tensioning the said element.

A still further object of the invention is the provision of a wrench of the above character which is simple and inexpensive in construction and which is eicient in use.

Other objects and advantages of the invention will become apparent as the description progresses.

In the accompanying drawing forming a part of this specication and in which like numerals are employed to designate corresponding parts throughout:

Figure 1 is a plan view of the improved wrench in gripping position on a nut,

Figure 2 is a side elevational view of the same,

Figure 3 is an end elevational View of the wrench,

Figure 4 is a transverse sectional view taken on line 4--4 of Figure 1, and

Figure 5 is a transverse section taken on line 5-5 of Figure 1.

Referring in detail to the drawing, wherein for the purpose of illustration is shown a preferred example of the invention, I0 generally designates the body of the wrench which is in the form of a flat elongated block having the inner end edge shaped to form a concaved serrated gripping jaw II. At one side of the jaw II the body block is formed with a laterally protuding shoulder I2 shaped to form a longitudinally directed slot I3 therethrough. The opposite outer edge of the body has, at one side, a beveled edge portion I3 which merges into the inner end of a bar I4 formed integral with and extending longitudinally from one side of this edge of the body. As shown to advantage at Figure 1 the body I0 has a diminishing taper toward the rear end and the bar I4 thereon, constituting a handle, is likewise preferably tapered. at its juncture with 55 At one side the bar I4,

Cin

the body, is shaped to provide a pair of opposed recesses I5 providing, therebetween, a longitudinally disposed apertured web I6. To this web .v through apertures in the knuckle and the web.

At the outer side the lever I1 is formed with a transversely disposed ridge 20 nearly opposed to the knuckle I8 and shaped to form a tie rod having its major portion spaced from the lever body. e

To one side of the body, adjacent the jaw II, is fastened, by a screw 2I, one end of an elongated gripping element 22 which may embody a strip of flexible metal disposed to extend, in looped formation, beyond the jaw forming edge and trained through the slot I3. One end portion oi the strip extends along the side of the body I0 and secured, by a rivet 23, in looped arrangement 24 about the tie rod 20 formed on the lever I1.

The head forming looped gripping portion of the strip 22 is designed to embrace, in conjunction with the jaw I I, an object such as the nut N of predetermined size and variable circumferential contour. To initially t the gripping end of f the Wrench upon the nut, as shown at Figures 1 and 2, the lever I'I, which substantially corresponds to the size of the handle bar I4, is swung laterally from the handle so that the looped gripping portion of the strip assumes its largest diameter. This head loop is then slidably fitted over the nut and the lever I'I swung inward toward the complementary b-ar I4 so as to tightly draw the gripping strip about the nut. As this strip is pulled taut it tightly grips the nut in coacting rer lation with the serrated jaw so that the nut may be readily turned by swinging the Wrench about its axis through the medium of the handle I4.

This construction provides a wrench which is simple and durable and which may be easily and conveniently disposed to engage a nut or other object for obtaining a tight grip thereon to turn the same.

It is to be understood that the form of my in-` vention herewith shown and described is to be taken as a preferred example of the same and that various changes relativer to the material, size, shape and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claim.

Having thus described my invention, I claim:

In a Wrench of the character described, an elongated at body having the edge at the inner end shaped to form a concave serrated jaw, an elongated handle forming bar projecting longitudinally from the opposite end of the body at one side thereof, the opposite side of the said outer end portion of the body having an inclined shoulder and an aper'tured web at the inner portion of the said shoulder, an angular lever having a longitudinal portion complementary to the handle bar, the said lever having an angularly directed knuckle at its inner end pivotally connected With the Web of the body, the inner end edge of the said lever being inclined with relation to the longitudinal portion thereof to coact with the inulined shoulder of the body for limiting the outward movement of the lever, a projection formed on one side of the body adjacent the jaw shaped to provide a longitudinally directed guide slot thereat. and la strap having one end secured to one side of the jaw and the intermediate portion trained through the guide slot with the opposed end fastened to the inner end portion of the lever, the saidv strap being disposed to form a loop at the inner end ci the Wrench adapted for gripping objects in association with the jaw on the inner end of the body the said lever and inclined shoulder arrang eme nt being disposed to maintain that portion of the strap adjacent the end secured to the lever in an approximately straight line position adjacent the side of the body.
